UNITED STATES PATENT @rrrca JAMES RUSS KITTREDGE,

OF OABTHAGE, MAINE.

SINK-SPOUT.

EPECIFICATION forming part of Letters Patent No. 300,574, dated June 17, 1884.

Application filed July 7, 1883. (No model.)

1'0 all whom it petty concern:

Be it known that 1, Joan G. COBURN, of South Carthage, in the county of Franklin and State of Maine, have invented a new and Improved Siiil:Spout, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved sink-spout provided with devices for thawing out the spout or pipe when the same is frozen.

The invent-ion consists in a vessel orcasing having a perforated top screwed in the sinkiioor, to the bottom of which vessel the wastepipe is attached. An additional pipe extends from the perforated top through or by the side of the water-pipe and around the top of the said additional pipe a cup is formed. If hot water is poured into the said cup it flows through the additional pipe and partly melts the ice in the waste-pipe.

Reference is to be had to the acconipz'uiying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a crosssectional view of my improved sinkspout. Fig. 2 is a plan view of the under side of the same. Fig. 3 is a seci tional view illustrating a modification. i

An externally-threaded cylindrical or like casing, A, is provided with aperi'orated top, B. The casing A is screwed into the sink- 1 bottom C until the perforated top plate, B, is I flush with the upper surfaceof the sink-bottom. The upper end of the si11k-spout or sink waste-pipe D is secured in the bottom of the casing A. A pipe, E, secured to the side of' the sink wastepipe D, is carried through the l casing A to the middle of the perforated top plate, B, from which it projects slightly. The pipe E can be made integral with or as part of the pipe D, or can be passed through the middle of the pipe D, as shown in Fig. 3. A cup, F, is secured on the top plate, B, around the upper end of the pipe E, which cup F is provided with a cover, G. The water poured into the sink flows through the perforated top plate into the vessel or casing A, and frointhe same through the pipe D. In case the water in the waste-pipe D freezes, the cover G is removed and hot water is poured into the cup F, which water flows through the pipe E and partly melts the ice in the pipe D. After a channel has thus been formed inthe ice in the pipe D, the hot water is poured directly into the casing or vessel 13, and then flows down through the pipe D and melts the remaining ice.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent- 1. The combination, with asink, of a vessel having a perforated top, a waste-pipe secured to the bottom of the said vessel, and an additional pipe extending from the perforated top of the said vessel along one side of the waste-pipe, substantially as herein shown and described.

2. The combination, with a sink, of a ves sel having a perforated top, a waste-pipe scoured to the bottom of the said vessel, an additional pipe extending from the perforated top of the vessel along one side of the wastepipe, and a cup secured on the perforated top and over the upper end of the additional pipe substantially as herein shown and described, and for the purpose set forth,

JOHX G. COBURN.
